BGM Pro transmission parts are ultra solid material. The wheels are made of high-alloy NiCrMo case-hardened steel (20NiCrMo2-2/ AISI8620) to withstand the toughest conditions.
The very good base material also withstands the highest engine power. The precisely defined surface hardening to 58-60HRC makes them extremely resistant to wear. Better than Piaggio parts. Consistently high quality. No compromises.

Suitable for all types of use, whether Tourer or Racer.
With 36 teeth one tooth shorter than the original 4 gear wheel of a PX200.
The gear connection to the fourth gear is noticeably improved.

Suitable for all transmissions with a flat cruciform. These gears can be recognized by the main shaft which has a circlip in front of the gears. The middle segment on which the cruciform rests is old at

  • PX (until 1984, cranked cruciform) : 5mm
  • Lusso (since 1984, flat cruciform): 6.5mm

The middle segments of the BGM gears are larger (approx. 1/10mm) and thus offer even more bearing surface for the cruciform.

TIP: Ideally combinable with the 64 teeth BGM Pro primary gear. In combination with a 24Z clutch sprocket, the overall gear ratio is significantly longer, but the gear step from three to four is shorter. Thus the full engine power can also be converted into final speed.
